My Hydrangeas Don’T Bloom Every Year; Why Is That?

A hydrangea’s failure to bloom can be due to various factors, including the root system not being suitable for your hardiness zone, incorrect pruning, or other factors. The root system may survive winter, but if the variety produces buds on last year’s stems, they are killed by extreme cold, resulting in no blooms the following year.

Incorrect pruning is the number one reason hydrangeas don’t bloom. It can be due to cold weather, fertilizer, incorrect pruning, or other reasons. To fix the problem, consider the following five potential reasons: too much sun, too little sun, excessive sun exposure, and improper pruning.

Excessive sun exposure can cause issues like leaf scorch, heat stress, and wilting. To prevent this, leave the plant alone and allow new growth to appear on the dead wood. Fertilizer that is too high in nitrogen produces lush foliage but does not encourage blooms. Pruning can also be a problem. Many hydrangeas bloom on old wood, and it may appear that someone has pruned all the old wood off. Endless Summer varieties can flower like that and flower on new growth, but hydrangeas don’t like getting too hot or dry out.

Pruning at the wrong time is another reason for no blooms. These plants just need deadheading and shouldn’t need any hard pruning. Even in early spring, if you see winter damage every year, it indicates the site is not favorable for big leaf hydrangeas. Try transplanting them in early spring to a more suitable location.

In summary, hydrangeas may not bloom as much as they once did due to various factors, including incorrect pruning, cold weather, and improper pruning. By addressing these issues, you can ensure your hydrangeas continue to thrive and produce beautiful flowers.

What does coffee do for hydrangeas?

Hydrangeas’ color is influenced by the acidity of their soil. The more acidic the soil, the more blue the blooms. To achieve the best blue hydrangea blooms, add coffee grounds to the soil. The pH level of the soil is crucial for hydrangeas to bloom. Higher acidity results in bluer blooms, while more alkaline soil produces pinkish flowers. Some hydrangea names, like Nikko Blue and Nantucket Blue, are influenced by their soil’s pH level. French hydrangeas are known for their globe-like blooms, which can be manipulated to suit color preferences.

To ensure blue blooms, ensure the soil is acidic. Fertilizers can help, but leftover coffee grounds can be just as effective and cost-effective. French hydrangeas are prized for their globe-like blooms, which can be manipulated to suit individual preferences.

How do you revive hydrangea blooms?

To revive hydrangeas, boil water and cool slightly. Cut the hydrangeas at a 45-degree angle and place them in a vase filled with hot water. Allow the hydrangeas to sit for at least an hour before repotting. Hydrangeas, derived from the Greek words “hydor” meaning water and “angos” meaning jar or vessel, require water to survive. Their woody stem can make it difficult for them to obtain the necessary water. Trim the stems at an angle and add a small slit to help them absorb more water. This simple hack can help bring your hydrangeas back to life.

What is wrong with my hydrangea?

The disease known as anthracnose can cause severe damage to hydrangeas, resulting in the formation of brown, tan, yellowish, or black spots on leaves and the development of cankers on stems and branches. In such cases, pruning and destruction of the affected areas are necessary.

What do hydrangeas look like in summer?

Endless Summer Hydrangea flowers are mophead flower heads that grow up to 9 inches across and have a mild floral fragrance. To encourage more blooms, plant them in optimal light and soil conditions, ensure they get enough water and the right fertilizer, and avoid extreme hot summers or late spring frosts. Despite these challenges, the flowers may bloom to their full potential the next year.

What is the best fertilizer for hydrangeas?

Organic, slow-release fertilizers for roses and hydrangeas are suitable for increasing the size and quantity of their blooms. Rose fertilizers, such as 15-10-10 or 10-5-5, provide the necessary nutrients for healthy growth, while hydrangeas require balanced fertilizers with a 10-10-10 ratio for healthy growth.

Growers often ask if they need to purchase different types of fertilizer for multiple hydrangea types. The answer is no, as the same type of fertilizer can be used for all types. However, adjustments may be needed if enhancing or changing the color of specific hydrangea blooms.

However, some types of fertilizer can cause harm, and Natalie Carmolli of Proven Winners® ColorChoice® Flowering Shrubs advises against using acidic fertilizers.

How can I tell what type of hydrangea I have?

Hydrangeas are popular landscape shrubs known for their large blooms in spring and summer. They are distinguished by their growth habit and foliage. Smooth hydrangeas have rounded, slightly heart-shaped leaves with a matte surface, while Big Leaf hydrangeas have large, elliptical, waxy, and serrated leaves. Identifying the correct hydrangea type is crucial for pruning at the right time to encourage the best bloom.

Common hydrangea types include Hydrangea macrophylla, Big Leaf hydrangeas, Smooth hydrangeas (native to Virginia), Panicle hydrangeas, Oakleaf hydrangeas, and Climbing hydrangeas. Proper identification is essential for successful pruning and maximizing plant growth.

What is the mistake for pruning hydrangeas?

Pruning hydrangeas is best done in late winter and early spring, making it a good weekend job during March. Pruning after winter frosts protects the plant from winter injury. Climbing hydrangeas should be left until early summer, as they produce flowers on old wood. Pruning too early may remove new buds before they bloom. Tom’s Guide offers expert editors to keep you informed and prepared for the prime growing season by pruning your hydrangeas at the right time.

How to get hydrangeas to perk up?

To prevent wilted hydrangea blooms, give them an ice bath by filling a sink with ice cold water and submerging the entire stem, flower head, and leaves for at least a couple of hours or overnight. Prepping your hydrangeas before cutting ensures they stay fresh from the start. Grow ideal varieties, such as bigleaf, oakleaf, and panicle hydrangeas, which are naturally better suited to producing wilt-resistant flowers. Some versions like lacecaps are less likely to last, while bigleaf, oakleaf, and panicle hydrangeas offer the best staying power when cut fresh.

Should hydrangeas be cut back?

Hydrangea paniculata, also known as panicle hydrangea, is a plant with conical-shaped flower heads that can be pruned back to just above a fat bud in fall, late winter, or spring. These plants produce buds in late summer to early fall, which will form next year’s flowers. To maintain winter interest in your landscape, it is recommended to wait until late winter or spring. Popular panicle hydrangeas include Quick Fire®, Limelight, and First Editions® Berry White®.

How to revive a hydrangea bloom?

To revive wilted hydrangea flowers, follow these steps: Trim a few more inches from the stem if the blooms don’t bounce back, submerge the entire flower in water for a quicker bounce back, use alum powder to improve water uptake, and cool the arrangement in a refrigerator for a few hours. Cut hydrangeas in the morning when the plants are most hydrated, use a floral knife instead of scissors or pruners to avoid crushing the stems, and condition the stems by placing them in water before and while arranging them.

Proper hydration and care are key to maintaining the freshness and longevity of the flowers in your arrangements. By following these steps, you can bring seemingly lifeless hydrangea cut flowers back to their full, beautiful glory.
